Are there specific times for taking birth control pills? If I buy birth control pills today, can I start taking them today? Thank you.

Dr. Lü Lizheng reply Obstetrics and Gynecology


Hello, it is recommended to start taking the contraceptive pills after the end of each menstrual period, approximately from the fifth day of your cycle.
Take one pill daily at a time that is convenient for you, either in the morning or at night.
However, it is best to take it at the same time every day, for example, consistently in the morning or consistently in the evening.
It is not advisable to start taking them at any random time after purchasing.
Sincerely, Dr.
Li-Cheng Lu, Attending Physician, Department of Obstetrics and Gynecology, Taoyuan Hospital, Ministry of Health and Welfare.

More Info


When it comes to starting birth control pills, timing is indeed an important factor to consider. Birth control pills, also known as oral contraceptives, can be initiated at different times depending on the type of pill and the individual's circumstances. Here’s a comprehensive overview of how to approach starting birth control pills.


Types of Birth Control Pills
1. Combination Pills: These contain both estrogen and progestin. They are the most commonly prescribed type of birth control pill.

2. Progestin-Only Pills (Mini-Pills): These contain only progestin and are often recommended for women who cannot take estrogen.


When to Start Taking Birth Control Pills
1. First Day Start: If you start taking the pill on the first day of your menstrual period, you will be protected against pregnancy immediately. This method is straightforward and is often recommended for those who prefer immediate contraceptive protection.

2. Sunday Start: Some women choose to start their pills on a Sunday, regardless of when their period begins. This method allows for a more convenient schedule, as it typically means that menstrual periods will occur on the weekends. However, if you start this way and it is not the first day of your period, you will need to use a backup method of contraception (like condoms) for the first seven days.

3. Quick Start: If you want to start the pill immediately after purchasing it, you can do so, but it is crucial to ensure that you are not pregnant. If you start the pill at any time other than the first day of your period, you should use backup contraception for the first seven days.


Considerations Before Starting
- Consultation with a Healthcare Provider: It is essential to consult with a healthcare provider before starting any form of birth control. They can help determine the most suitable option based on your health history, lifestyle, and any potential contraindications.


- Health History: Certain medical conditions or risk factors may influence the choice of birth control. For example, women who smoke and are over 35, or those with a history of blood clots, may be advised against using combination pills.

- Side Effects and Risks: Be aware of potential side effects, which can include nausea, headaches, mood changes, and breast tenderness. Most side effects are mild and tend to resolve after a few months of use.


Conclusion
In summary, if you purchase birth control pills today, you can start taking them immediately, but you should be mindful of the type of pill and your current menstrual cycle. If you are not starting on the first day of your period, using a backup method for the first week is advisable to ensure effective contraception. Always consult with a healthcare provider for personalized advice and to discuss any concerns you may have regarding birth control options. This approach will help you make an informed decision that aligns with your health needs and lifestyle.
